Rails - Dec 2005 - Error: [Object]Controller: missing default helper path [controller]_helper

Hello,

I seem to have run into a problem that I can''t seem to make any  
headway on. I''ve searched the mailing archives, google''d for
the
appropriate keywords and have checked up with the folks on IRC but I  
can''t seem to find a solution.

My problem is as such. I have a web application that has various  
controllers which work fine. I''ve added a new controller for the  
object Event, which at this point is very simple and reads as:

class EventController < ApplicationController
   layout  ''standard''

   before_filter :authorize

   # method handle used for handling adding new events to the system
   def add
     @locations = Location.find_roots
     @arts = Art.find_all
     @event = Event.new( @params[:event] )
     @event.user  = @session[:user]

     if @request.post? and @event.save
       redirect_to :action=>:view, :id=>@event.id
     else
       @event.errors.each_full do |msg|
         logger.error( "error while saving event: #{msg}")
       end
     end
   end

end

When I call http://localhost:3000/event/add/ it loads the correct  
view which has a variety of form elements. When I commit this form I  
get a blank page, and the output of WEBrick reads:

127.0.0.1 - - [15/Dec/2005:11:57:06 PST] "POST /event/add HTTP/1.1"  
500 0
http://localhost:3000/event/add/ -> /event/add

The ONLY line which gets appended to the development.log is:

EventController: missing default helper path event_helper

Does anybody have any ideas what is going on? I''ve restarted the  
server numerous times and have even (on a tip from the mailling list  
archive) rebooted. Any help would be welcomed with much praise...

my first guess is you probably did not use ''script/generate controller
event'' to create your controller, as that should have created the
app/helpers/event_helper.rb file as well

but i could be wrong.

Hmm... good guess - I didn''t think it was required, since my other  
controllers work without it, and my controller works, just not when I  
post to the add method.. Anyhow - to be safe - I regenerated the  
controller from scratch and re-ran it. The problem turns out to be  
the same as before, only now while I still get a 500 response and a  
blank page in my browser there is no messages whatsoever added to the  
development.log...
